Here’s a fun new product that lets you create a customized climbing structure for your cats. It’s the Catty Stacks, designer cat house system. These super strong corrugated cardboard boxes can be connected in three dimensions to create all sorts of configurations for climbing, perching, playing, napping, and hiding. The nice folks at Catty Stacks sent us a set to test out and they were an instant hit. Here are Simba and Dee checking out the new play station:

The boxes ship flat and are really easy to set-up, just unfold and insert some tabs into slots and you’re ready to go. The special corner design allows you to clip the boxes together (clips are included) to create a nice sturdy structure. Once the boxes are clipped together, you can lift the whole stack to move it (just make sure there aren’t any cats inside!)

Holes on the side of the boxes allow kitties to enter and exit and connect from one box to the next. When two boxes are clipped together, you can remove a larger portion of the side panel to create a more spacious inner lounge area. When boxes are stacked on top of each other, the vertical access holes are staggered, making it easy for kitty to get her footing as she climbs up through the boxes. The thing I’m most impressed with is the strength of the double thickness cardboard. This is some of the strongest cardboard I’ve seen, so the Catty Stacks should last a long time.

There are a number of accessories you can purchase as add-ons for your Catty Stacks, including a crawl tube that connects between two boxes, special felt pillows for extra comfort, and an animation wand that connects easily to one of the accessory points and has a clip on the end to attach kitty’s favorite toy. Here’s Theo getting ready to attack the dangling toy:

The boxes come in light pink, chocolate brown, sky blue, pistachio green, and white, all printed with 100% soy-based inks. The cardboard used is also 100% recycled and recyclable. You can choose any combination of colors when ordering the boxes in kits ranging from one box for $17.99 US, to ten boxes for $129.99 US.

Cardboard is the preferred material for all things associated with cats in our house. And the Cardboard Climber looks way better than the assortment of boxes left by the UPS man. These are sure to be a hit in our house!

Oh wow, this is EXACTLY what I’ve been looking for. My kitty and I are moving to the Caribbean for 2 years and I’m having a hard time figuring out how I’m going to ship all of her cat toys. These are perfect for travel and look like soooo much fun!

This is such a cute idea. I remember building a cardboard box playground for my kitties years ago, using lots of duct tape and string. It didn’t last long, but they sure did have a blast with it. I’d definitely love to win this, and my six kitties would have an absolute blast playing with it.

Cool! I don’t know where I’d put them, but considering there’s always space for a cardboard box or two for my cat to play in, I’m sure we’d come up with something. He looooooves boxes, so as long as these are big enough for a big cat (around 18 pounds) I’m sure he’d love them.
